Coinfection with virus alters Phomopsis subordinariaperformance
We investigated the effect of PlLV coinfection on P. subordinariawithin-host infection load (measured as AUDPS), and transmission
potential (measured as pycnidia density) in an inoculation experiment
with two P. subordinaria strains (P29 and P43). The two strains
differed significantly in their AUDPS with strain P43 outperforming
strain P29 (Table 1; Fig 2B). For both strains, within-host infection
load (measured as AUDPS) was lower under coinfection with PlLV than whenP. subordinaria infected the host alone (Table 1; Figs. 2AB).
Pycnidia density was significantly higher under coinfection than under
single infection, while P. subordinaria strains did not differ in
their pycnidia densities (Table 1; Fig. 2C).
